Specification of I zetters Patent. Pgfliented Oct, 4, 1921,

Application filed April 16, 1921. Serial No. 462,059.

To all whom it may concern 1 Be it known that I, ONESIME J. HALLEE, acitizen of-Canada, residing at Chisholm, in the county of Franklin andState of Maine, have invented certainnew anduseful Improvements in DamConstructions, of which the following is a specification, referencebeing had to the accompanying drawings.

This invention relates to improvements in dam constructions and moreparticularly to a construction of the flood gate type.

An important object of the invention is to provide a construction ofthis character wherein when the automatic flood gate is moved to thedischarge position all of the water passing through the gate will passover the same so as to prevent the collection of debris at the base ofthe gate, preventing proper closing of the same.

A further object of the invention is to provide a novel constructionofflood gate which may be readily placed upon a stream bed withoutnecessitating the construction of an expensive and costly base therefor.

Other objects and advantages of the invention will become apparentthroughout the course of the following description.

In the accompanying drawings, wherein for the purpose of illustration isshown a preferred embodiment of my invention and wherein like referencecharacters designate like parts throughout:

Figure 1 is a fragmentary perspective of a flood gate constructed inaccordance with my invention.

Fig. 2 is a side elevation thereof, and

Fig. 3 is a section on the lines 33 of Fig. 2.

Referring now more particularly to the drawings, the numeral 10indicates a substantially vertical wall formed upon a bracket 11 andconnecting at its upper endwith a wall 12, inclining upwardly from theupper end of the vertical wall 10 and extending in what might be termeda downstream direction therefrom.

At the junction of the vertical and inclined walls 10 and 12, a socket13 is formed,

for the reception of a shaft 14 the shaft beingheld in position in thesocket by means of straps 14 bolted through the vertical and inclinedwalls or some similar expedient. For each flood gate section a pair ofthe brackets 11 are provided.

The numeral 15 indicates a flood gate formed of vertical strips suitablybraced passage of the water thereover.

as at 16, and pivotally connected to the shaft 14 by means of bearings.17 secured to the flood gate 15 and through which the shaft 14 extends.Attention is directed to thefact that the mounting of the shaft 14 inthe sockets. l3 permits of the engagement of the face of the flood gateflatly with the walls of the vertical and inclined sections 10 and 12,these sections being notched, as at 10 and 12 to accomodate the braces16. The brace 11 will be sufficiently widely spaced so that the floodgate 15, pivoted therebetween, will cover approximately half 7 of thewall of the braces with which it coacts, thereby permitting of thearrangement of a plurality of flood gates in series as shown in Fig. 8,without forming between the flood gates a space necessitating therovision of a vertical stop wall to prevent ow. The lowerends of thevertical walls 10 of the adjacent brackets 11 are connected by braces18, and the upper ends of the inclined walls 12 thereof are connected bybraces 19 which receive and support the upper and lower edgesrespectively of the flood gate 15 so that when the same moves to eitheropen or closed position it is supported by both the shaft 14 and a brace18 or 19, rendering the same very solid.

The operation of the flood gate is identi the gate remaining in theposition shown in Fig. 2 until the water reaches a predetermined heightwhen it automatically swings to the position shown in Fig. 1, permittingIn order to prevent the collection of debris at the base of the floodgate in such a manner as to prevent proper closing of the same, Iprovide in advance of the flood gate a baflie grid 20 formed of spacedstrips 20*, suitably braced as at 21, with which the gate 15 coacts whenin the open position as indicated in Fig. 1, to bar the passage ofdebris be-- neath the gate.

The construction hereinbefore set forth being capable of many changesand variations with respect to size, shape and arrangement of thevarious parts hereinbefore set forth without in any manner departingfrom the spirit of my invention, I do not limit myself to the specificstructure thereof except as hereinafter claimed.

What I claim is:

1. An automatic flood gate comprising a. pair of spaced supports, eachembodying a substantially vertical Wall and a wall connected to andinclining upwardly from the same, a brace connecting the vertical wallsof said supports at the lower ends thereof,

a second brace connecting said inclined walls at the upper ends thereof,a pivot member secured at its ends to'said supports at the juncture ofthe vertical and inclined walls thereof, and a flash board pivotallymounted upon said member and swinging to alternately engage said braces.r

2. The combination with a normally vertical horizontally pivoted floodgate adapted to automatically shift upon the pivot thereof a to openpositionto permit passage of the water retained thereby when the samehas attained a predetermined depth, of means coacting with the lower endof the flood gate for preventing the passage of debris therebeneathwhile in such open position.

3. The combination with a normally vertical horizontally pivoted floodgate adapted to automatically shiftjupon the pivot thereof to openposition to permit passage of the water retained thereby when the samehas attained a predetermined depth, of an inclined baflie grld'arrangedadjacentsaid flood gate and coacting with the lower end thereof toprevent'tlie passage of debris therebeneath when the gate is in openposition.

In "testimony whereof I hereunto aflix my signature.
